A DIY demonstration of a fan-and-screen mosquito trap that uses carbonated water as a CO2 attractant. The creator reports catching about 8,000 mosquitoes in two nights.

A short NASA Goddard visualization from the GEOS-5 model showing a year of atmospheric carbon dioxide moving around the globe. It shows plumes from sources, hemispheric differences and seasonal swings as plants grow and die back.

A Smarter Every Day episode from aboard a nuclear submarine on how the crew makes breathable air. It covers oxygen generation from seawater, oxygen candles and CO2 scrubbing with amine.

Tom Scott features Kurtis Baute inside a sealed homemade biodome as carbon dioxide builds up, showing how stale air with elevated CO2 affects cognitive function. Sources include studies on CO2 and cognitive scores.

Sabine Hossenfelder explains how the greenhouse effect actually works, given that infrared is mostly absorbed low in the atmosphere already. She walks through why more CO2 still warms the surface.

David Heinemeier Hansson explains what he learned about indoor air quality after his new house made his family sick. He covers CO2, VOCs, off-gassing, HVAC and ventilation, and cognitive effects, presented at a Basecamp meetup.

Veritasium debunks common climate change myths in under seven minutes, with references to NASA and published research. Topics include CO2 sources, sea ice and 1970s predictions of cooling.

A 2015 interview in which physicist Freeman Dyson, then 91, argues that global warming concerns are exaggerated, that CO2 is beneficial and that climate models oversimplify complex systems. It is posted on a channel that opposes climate consensus.

Engineering Explained compares the lifetime CO2 emissions of a Toyota RAV4 Prime plug-in hybrid with a Tesla Model Y, looking at break-even mileage and whether electric cars are worse for the environment.

Veritasium examines whether food has become less nutritious, weighing soil depletion, selective breeding and rising atmospheric CO2. It evidences nutrient decline even in weeds over a century and ties it to faster plant growth.

Researcher Kamal Meattle describes how an arrangement of three common houseplants placed in specific spots can measurably clean the air in a home or office. It is a short TED talk based on his work in a plant-filled building.

Everyday Astronaut's Tim Dodd runs an hour-long, data-driven analysis of what rockets actually emit and how that compares with airliners and other industries. It breaks down exhaust by propellant type, per-passenger and total emissions, and ways launches could be cleaner.

A 2007 Channel 4 documentary by Martin Durkin arguing that human-caused global warming is overstated or a scam. It features contrarian scientists such as Richard Lindzen and promotes sunspot and cosmic-ray explanations for temperature change. Its claims are rejected by mainstream climate science.

Destin Sandlin of Smarter Every Day undergoes hypoxia training and experiences his own impaired thinking as oxygen is withdrawn. The video shows how quickly and unnoticeably oxygen deprivation degrades judgment, illustrating why you put your own mask on first.

Carl Sagan's December 1985 testimony to Congress on the greenhouse effect, about 15 minutes long. He lays out CO2 warming, the risk of runaway effects and the danger of continued coal burning.

Freeman Dyson's 2005 Boston University talk on heretical views about science and society. He questions prevailing dogmas, including his argument that climate and CO2 are a land management issue.

Tom Chi gives the opening talk of a Foresight Institute competition on clean energy and clean air, framing excess CO2 as a carbon debt to repay and discussing large-scale tree planting, including by drone.

Elon Musk gives students at the Sorbonne a short, simple explanation of climate change and carbon emissions shortly before the 2015 COP21 conference in Paris. He covers why CO2 accumulation matters and argues for a carbon tax.

Technology Connections tests how quickly gas, induction and standard electric stoves boil water, with CO2 measurements and a discussion of the advantages and disadvantages of each.

A four-minute demo of the greenhouse effect showing how increased carbon dioxide raises temperature. It uses a simple setup that is dramatic and easy to understand.

SpaceX's September 2019 Starship update presentation, where Elon Musk describes the design and development of Starship and Super Heavy. It covers construction and plans for reusable orbital rockets.
